What Is Diverticulitis?

Learn about diverticulitis from gastroenterologist Lisa Ganjhu, M.D. in this Howcast video about stomach problems and digestive disorders.


So, in order to understand what diverticulitis is you need to understand what a diverticulum is. So diverticulum are little out pockets within the colon that occur with patients that have constipation or have some genetic predisposition to developing it. Now, within those pockets you can get seeds and stool to go into those pockets. Now, diverticulitis happens where there's stool, or some sort of obstructing lesion, that falls into one of these pockets and causes some infection and inflammation. And it can present with pain, and fever, and some constipation. Diverticulitis most commonly happens in older individuals that have chronic constipation and don't exercise. By exercising, eating high fiber, and not getting constipated, those pockets actually empty out so that there's a lesser predisposition for developing infection or diverticulitis.
